2. General information
Company name : Saraj – Komerc d.o.o.
Address : Batuški Lug bb - Industrijska zona
70240 Gornji Vakuf – Uskoplje
Activity : Production of cover assemblies for fuel filters, springs and tubes
Property : 100% private
Year of foundation : 1983.
General Manager : Emir Čolić

3. Infrastructure
Three production buildings on two locations,
with a total shop floor area of 15.500 m2.
Company’s infrastructure provides conditions for
business development in all fields of work.

4. Infrastructure
After it’s rebuilding, the whole facility
of „Tvornica Opruga” manufacturing
site is available for new projects.
Fully automated Zn/Ni galvanizing line
which is installed on this location
provides for our competitiveness in the
market, with opportunitites for new
projects and continous growth and
development.

5. Products and services
Our range of products includes cover assemblies for fuel filters, springs, tubes for
Common Rail Pumps and Coolers and turned parts. We offer galvanizing and
brazing services to our customers.

6. Products and services
Besides the main products, production capacities allow us to produce various
stamped parts. Parts are produced according to customer drawings or according
to a sample, in which case we develop part drawings.
Our experience in stamping and tubing allows us to develop small tools for
internal use and for our customers.
We provide services of coordinate measuring and different chemical tests in our
lab.

7. Hydraulic components
We produce hydraulic components for known
customers. Parts are produced from steel and stainless
steel.
Hydraulic components are produced
by turning on CNC machines or cold
forming on machines that are
produced by our skilled personnel.

8. Stamping
More than 40 excenter and hydraulic presses ranging from 10 to 400 tons allow
us to produce different stamped parts. Stamping presses are primarily used for
production of covers which are then assembled into cover assemblies. Materials
used are steel and stainless steel.

9. CNC machining
More than 20 CNC machines produce sub-components which are assembled into
cover assemblies and final products which are then delivered to our customers.
Capacities allow us to produce parts from ferrous and non-ferrous metals.

10. Tubing
Tubing involves different processes such as cutting, chamfering, deburring,
reaming, cold forming and bending. Different types of tubes produced from steel
and stainless steel are used in cover assemblies, but also as final parts which are
assembled into Common Rail Pumps and Coolers by our customers.

11. Assembly and brazing
Sub-components are assembled into cover assemblies
and brazed in brazing ovens with temperatures up to
1100° C. Brazing ovens are dedicated to steel and
stainless steel parts.

12. Tool room
Tools for tube forming and bending, stamping,
plastic die moulding and gauges for the running
production are produced in our tool room. Tool room
capacities are also used for maintenance of the
existing stamping tools.
Processes include turning and milling, CNC milling,
coordinate grinding, centerless grinding, EDM and
wire-cut EDM and heat treatment.
Tool room provides services to customers as well.

13. Production of springs
At it‘s foundation, Saraj-Komerc was producing primarily springs. Even though it
makes a very small portion of our current production, spring manufacturing is
still one of our specialities. We produce all types of springs from material ranging
from Ø0,2 to Ø16 mm in diameter. Springs are produced from patented steel
wire and from stainless steel wire. Production includes galvanizing and
passivation of springs. Springs are tested internally for force and deflection.

14. Production of hinges and
springs for garage doors
We provide services of production of hinges and springs of different dimensions
for garage doors. Our offer includes springs produced from matertial ranging
from Ø5 to Ø12 mm in diameter, and in different lengths.
Springs are delivered oiled and packed in a stretch foil, in accordance with our
customer requirements. Materials used are imported from the EU countries .
Material certificates are delivered upon request.

15. Galvanizing
“Saraj – Komerc” has three galvanizing lines. Two galvanizing lines are allocated
for Zinc and Tin galvanizing. Third galvanizing line which is fully automated is
used for Zn/Ni galvanizing, which is widely used in the automotive industry.

16. Racks are used in the acidic tin
galvanizing. Coating thickness
distribution is good, with decorative
appearance obtained. Corrosion
resistance is good.
Tin galvanizing
This type of coating is often used in food industry. Tin galvanizing is partially
used for our products, and mostly as services for customers.

17. Acidic and alkaline Zn galvanizing
Acidic Zinc galvanizing
Drums and racks are used for acidic galvanizing. Fast coating process and
decorative appearance are characteristic for acidic galvanizing.
Additional processes include blue and black chromating (using CrIII) and sealing.
Alkaline Zinc galvanizing
Racks are used for alkaline Zinc galvanizing. Zinc
coating process is slower with optimum coating
thickness distribution. Compared to acidic Zinc
galvanizing, alkaline Zinc galvanizing has better
corrosion resistance.
Additional processes include blue and black
chromating (using CrIII) and sealing.

18. Zn / Ni galvanizing
Automated Zn/Ni galvanizing line was installed in order to meet requirements
from strategic customers.
Zn/Ni galvanizing was developed to replace Cadmium coating which is deemed
unacceptable for the environment. Zn/Ni galvanizing not only replaced cadmijum
coating but also exceeded it in terms of quality. Corrosion resistance of Zn/Ni is
up to 10 x longer compared to zinc and up to 3 x longer compared to cadmium.
Zn/Ni coating can in terms of salt spray test according to ISO 9227 reach
following values:
• More than 500 hours to white corrosion,
• More than 1000 hours to red corrosion

19. Quality and ecology
ISO 9001 Quality Management System has been implemented in 2002. and ISO
14001 Environment Management Systemhas been implemented in 2007.
All employees are continuously trained on importance of ecology and safe
environment.

20. Quality and ecology
Activities on implementation of ISO/TS
16949 are in progress, and current Rules of
quality and system procedures are in
accordance with ISO/TS 16949.
Certification phase is planned for 2015.

21. Measuring lab
Measuring lab includes all the equipment
necessary to assure quality required by
our customers.
Measuring equipment includes CMM
(Coordinate Measuring Machine)
contourograph, roughness measuring
machine, shadowgraph.

22. Measuring lab
Besided the mentioned equipment,
we have X-Ray machine for coating
thickness measurement.

23. Waste water treatment
Waste water treatment lines are automated facilities where output results meet
regulations for output parameters such as concentration of heavy metals or pH
value.
Measurements are read online and present real time values.

24. Waste water treatment
Through two automated waste water treatment lines, Saraj – Komerc shows it’s
dedication to preservation of the environment and high level of ecological
consciousness that will be promoted in the future.

25. Social responsibility
